Synapse

Synapse is the "New Continent" that Sugata was researching the whole time and found out that this is connected to Tomoki's dream. The only way for them to enter Synapse is the Dive Game. In his findings he finds that some people on earth are not "real" and they are just angels dreaming. The "Man of Synapse" sent Nymph From here to take Ikaros back here. The plan was a failure, and Nymph joined Tomoki. He alse sent Astrea to kill Tomoki. That plan was a failure as well, and Astrea broke the chain on her choaker, meaning that she left the Man of Synapse. later in the anime, the Man of Synapse created the 2nd generation angeloids, an even more powerful version of the first generation angeloids. The first of these brand-new 2nd generation angeloids we saw was Chaos, an angeloid who did not have wings, but a floating device that is behind her. The Man of Synapse also sent her to kill Tomoki.
